AVG took the same path, and was replaced in the world of free av when they too started making bad decisions. The fact Avast has taken it upon themselves to automatically install it during today's upgrade, suggests you're taking a turn for the worst and letting corporate greed be the decision making factor now. If I wanted the Google Chrome browser I would have installed it myself! Today's stunt though has opened my eyes, and I am now re-evaluating your place on my PC, and everyone else I knows PC. Even after a few more companies jumped into the FREE AV market, I still continued to use Avast even though I knew it was becoming more and more taxing on my PC's resources with all the extra's.
Avast in my books used to be ranked at the top, have recommended you guys countless times, have personally uninstalled tons of AV software and replaced it with Avast as it was my personal preference, and choice.
